The program graphs angular, horizontal, and bi-level projectiles given 2 of these: launch angle, total velocity, x-velocity, or y-velocity (and starting height for bi-level) and quits. You can graph DistX/DistY, Time/DistY, Time/DistX, Time/Yvel, and DistX/DistY. You use [2nd] [Calc] functions to find when it lands, where it lands, its maximum height, when its maximum height is reached, where it is at a certain time, etc.
